New gf has type 1

Hey everybody hope this is a place I can post and get help. I recently started dating a girl that has type 1, she’s only 20 and was diagnosed at 16. I went to a dr appointment with her to learn more about type 1. She still has trouble coming to terms that she has it. She says she a bad diabetic and forgets to check her levels. What are some ways I can help remind her and keep her on track. She has a pump and I have the follow app to keep track of her levels. I don’t want things to get worse for her in the future. Also any info that I could use or learn about is helpful.
